A massive fire collapsed an Interstate 85 (I-85) bridge in Atlanta, Georgia, United States, on the evening of March 30, 2017.

After the 92-foot-long (28 m) section collapsed, I-85 was closed to traffic for 43 days between its split with I-75 and the interchange with State Route 400 (SR 400) — approximately two miles (3 km).

[3][4] An NTSB report determined that the Georgia Department of Transportation contributed to the incident by unsafely storing materials under the bridge.

[1] On March 30, 2017, a massive fire collapsed a section of the I-85 freeway viaduct in Atlanta, Georgia, stranding motorists for miles during rush hour traffic.

Atlanta Mayor Kasim Reed described the situation as a "transportation crisis" and Georgia Governor Nathan Deal declared a state of emergency.

[6] The fire started at approximately 6:05 p.m. under the highway bridge, at a state-owned storage area which contained high-density polyethylene (HDPE) and fiberglass tubing.

[15] Two weeks after the bridge collapse, President Donald Trump met with first responders from the incident, commending them for preventing casualties.
